Hybrid mounting providing sealing and nvh function for structures

Abstract

A hybrid mounting system is provided for mounting components together with a gasket there between. The mounting system provides soft or hard mount bolt locations, depending on application, at areas identified as high frequency path or problem areas while hard or soft mount bolt connections, depending on application, are utilized at areas identified as non problem or path areas. The hybrid mounting system can be utilized in applications involving industrial machinery, automotive applications and other applications where two components are mounted together with a gasket there between.

1 . A component mounting system, comprising:
 a first component having a first plurality of bolt holes therein;   a second component having a second plurality of bolt holes therein;   a gasket disposed between said first component and said second component and having a third plurality of bolt holes therein in alignment with respective ones of said first and second plurality of bolt holes; and   a plurality of bolts inserted in respective ones of said first, second and third bolt holes for securing said first and second components together, at least one of said plurality of bolts defining a soft mount and at least one of said plurality of bolts defining a hard mount, wherein said at least one of said plurality of bolts defining a soft mount is located at a location corresponding with an NVH path or problem area.   
   
   
       2 . The component mounting system according to  claim 1 , wherein said at least one bolt defining a soft mount includes an elastomeric grommet disposed between a head of said at least one bolt and said first component. 
   
   
       3 . The component mounting system according to  claim 2 , wherein said at least one bolt defining a hard mount includes a head portion disposed directly against said first component. 
   
   
       4 . A method of sealingly mounting a first component to a second component for improved vibration characteristics, said method comprising:
 determining one or more vibration path problem areas between said first component and said second component and determining one or more vibration path non-problem area between said first component and said second component;   mounting said first component to said second component with a gasket disposed there between;   inserting a plurality of bolts into said first and second components, said bolts located at said determined vibration path problem areas defining a soft mount and said bolts located at said determined non-problem areas defining a hard mount.   
   
   
       5 . The method according to  claim 4 , wherein said bolts defining a soft mount include an elastomeric grommet disposed between a head of said bolt and said first component. 
   
   
       6 . The method according to  claim 5 , wherein said bolts defining a hard mount include a head portion disposed directly against said first component.
